My research consists in developing models of the economy that incorporate heterogeneity and bounded rationality in the agents' behaviors and expectation formation process. I have been also using lab experiments to gain empirical insights on those behaviors.

The resulting models include agent-based models and learning models with heterogeneous and interacting agents. I have used those models for the analysis of macroeconomic questions, in particular monetary and fiscal policy design, central bank communication, and prudential policy and financial regulation.
